IMPROVEMENT IN THILL-COUPLING.

The Schedule referred to in these Letters Patent and making part. of thesame.

To all whom yit may concern Be it known thatwe, WILLIABI H. Coxand-THEornI- LUs LAROUCHE, of \\'illamstown, in the county of Oswego,and State of New York, have invented a new and uscfnl Improvement inTMll-Coupling; and we do hereby declare that the following is n. full,clear, and exact description thereof, which will enable others skillediu the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specification.

This invention relates to a new and useful impl-owrnent in device forcoupling thills to huggies or other vehicles; and consists in theconstruction and arrange- 'xnent hereinafter described. A

line x a'.

Similar let-ters of reference indicate corresponding parts.

A.. is the draw-iron, which is ihstened to the axle B by means oftheclip C.

D is the shank, or part which is. att-ached to the thills ofthe vehicle.

e is a collar on the shank, and

f is a groove in its end or journal, which enters the socket of thedraw-iron.

Gis the socket, which is closed'at one. end. The collar e closes theother end, so that sand and dust are excluded.

H is a screw, which passes through the socket G, the end of which screwenters the groove f in the shank, which arrangement prevents thewithdrawal of the shank, except when the thills are elevated to near avertical position; then the slot (from the end of the shank into .thegroove f) will receive the end of the screw, and allow the shank to hewithdrawn.

On the screw there is a jam-nut, i, which, when the screw is properlyadjusted, is turned tightly down on to the. socket, which secure-lyholds the screw to its place.

T hc shank, in attachingl the-thills to the earliage, is sprung into thesocket h v springing the thills, and it will be seen that the springritself is suitieicnt to keep the thills in place and to prevent rattlingwithout the screw H,'but we prefer to use the screw in addition, as itmakes the coupling more complete.

This is a cheap and simple arrangement, not lliable to break or get outof order, and perfectly sure am safe in its operation.

Having thus described our invention, l v

\Ve claim as new, and desire to secure by Letters Patentf- 1. rI heimproved draw-iron A, having a chamber enclosed on all sides except theend which is covered by the cap e, as shown and described.

` 2. The combination of screw H and jam-nut 'i with the draw-iron, and ashank provided with the cylindu'cal' groove S, arranged as set forth, toprevent rattling.
